Even when he teams up with an established comic actor, Fassbender ends up in a serious movie, like when he appeared in Steve Jobs alongside Seth Rogen as Steve Wozniak.

"We'd met before, I was a fan of his work. I think I threw a blueberry at him actually, it was at one of these dinners and he was at the table across the way and so that was our introduction," he recalled.

"So, when we were on Steve Jobs, he said, 'I thought we'd work together at some point but I thought it would be in one of my movies'. So yeah, maybe at some point."

Before we can see Fassbender in full comedy mode though, we've got Alien: Covenant to enjoy, and he's been filling us in on what David has been doing in the ten years since he finished Prometheus as a head in a bag.

"He's been doing some gardening, trying to find some love in space," he explained.

"Obviously there's lots of interesting things about David but I had fun playing with the idea that in his programming there's some human personality traits that have been introduced to him. To play around with that concept was fun."

Alien: Covenant creeps into UK cinemas tomorrow (May 12) and is released in US cinemas on May 19.
